FIELD OF THE TECHNICAL
[0001] The present disclosure relates to smart watch technology field, and particularly
to a smart watch and a display method for a smart watch.
BACKGROUND
[0002] For a existing smart watch, a display screen covers a wristband of the smart watch,
and the whole display screen is used to display content. For example, the display
screen takes up the outer surface of the smart watch or a dot matrix screen covers
the whole wristband of the smart watch. As shown in FIG. 1, when the smart watch 10
displays an image, the image 12 nearly takes up a half of the screen of the smart
watch, and goes across 180° in space. When a user wants to watch content, all display
regions of the ring-shaped display screen will be lighted to allow the user to perform
an operation.
[0003] The shortcomings of this solution is that when the integral part of the wristband
of the smart watch is used as the display region, not the whole display region is
within the user sight (only the top part of the smart watch can be seen by the user).
When the whole display region is lighted normally, the region not within the user
sight is not useful for the user. For example, as shown in FIG. 1, when the user views
the image 12 from up, the user can only see the image within the scope of 90 degrees,
and words at two ends of the image 12 cannot be seen by the user. Therefore, there
is no need to light the region which cannot be seen by the user, otherwise additional
power consumption will be generated, and burdens of the smart watch will increase.
[0004] Also, not the display of all kinds of information will take up the whole screen.
When a message which length is smaller (for example, time or a simple short message)
is displayed, lighting the whole screen normally will consume a great power of the
smart watch, thereby decreasing experience of using the smart watch.
[0005] Therefore, what is needed is a new display technology. By means of the technology,
which region of the smart watch can be seen by the user can be determined according
to a posture of the smart watch, and accordingly the region is set to be a normal
display region of the smart watch. Based on this, adjusting brightness of display
regions can be realized, to prolong the battery life of the smart watch, and improve
user's experience.
SUMMARY
[0006] Based on the above mentioned problems, a display technology is provided. By means
of the display technology, which region of a smart watch can be seen by a user can
be determined according to a posture of the smart watch, so that the brightness of
the region can be set to be the normal brightness, and the brightness of the other
region which cannot be seen by the user can be reduced, thereby prolonging the battery
life of the smart watch and improving user's experience.
[0007] The present invention provides a smart watch which includes a posture monitoring
unit configured to monitor a posture of the smart watch in real time and determine
a normal display region of the smart watch according to the posture, and a displaying
unit configured to display content to be displayed in the normal display region.
[0008] In the technical solution, the posture monitoring unit can be one or more G-sensors
and can detect the posture of the smart watch in space. For example, if lie flat,
a ring of the smart watch is parallel to the horizontal plane. When the ring of the
smart watch is vertical to the horizontal plane, it indicates that a user makes the
smart watch up to watch the time. When the user watches a ring arranged vertically,
the user can only see a portion of the ring which faces himself/herself. Thus when
the smart watch is in this posture, if the user watches the smart watch, the user
can only see a portion of the smart watch. Accordingly, the smart watch can determine
which portion can be seen by the user according to the current posture, for example,
the top region, or the inner region of the smart watch which is facing the user. This
portion will be regarded as a normal display region and will be lighted in first preset
brightness (for example, normal display brightness) to display an image, and the other
region will be lighted in lower brightness to display an image since the other region
cannot be seen by the user.
[0009] In the technical solution, preferably, the displaying unit may include a brightness
setting unit configured to set the brightness of the normal display region to be the
first preset brightness and set the brightness of the other region to be second preset
brightness which is less than the first preset brightness.
[0010] In the technical solution, when the user wants to view the image displayed in the
other region, the user can rotate his/her wrist to adjust the posture of the smart
watch, to make the smart watch to redefine the normal display region, thus the region
which can be seen by the user can be always lighted in normal brightness and the region
which cannot be seen by the user can be always lighted in lower brightness, thereby
reducing power consumption of the smart watch and prolonging the life of the battery
of the smart watch.
[0011] In the technical solution, preferably, the posture monitoring unit includes an included
angle determining sub-unit configured to compute the included angle between the plane
where the ring of the smart watch stays and the horizontal plane and determine whether
or not the included angle is within a preset angle range, and a region setting sub-unit
configured to set the region the center of which is a vertex of the ring within the
space and the area of which equals to a preset value to be the normal display region
when the included angle determining sub-unit determines that the included angle is
within the preset angle range.
[0012] In the technical solution, the posture of the smart watch can be determined by determining
the included angle between the ring of the smart watch and the horizontal plane. When
the included angle is within the preset angle range (e.g., 60° -90°), it indicates
that to a greater degree the smart watch is vertical to the horizontal plane, and
it can be determined that the user is watching the content displayed on the smart
watch, and the top portion of the smart watch is set to be the normal display region.
[0013] It should be noted that the way of determining the posture of the smart watch can
include but not limited to determination of the included angle.
[0014] In the technical solution, preferably, the brightness setting unit is further configured
to set the brightness of all the regions of the smart watch to be the second preset
brightness when the included angle determining sub-unit determines that the included
angle is less than the preset angle.
[0015] In the technical solution, when the included angle is less than the preset angle,
it indicates that to a greater degree the smart watch is parallel to the horizontal
plane, and it can be determined that at this point the user does not watch the content
displayed on the smart watch, thus the brightness of the whole display region of the
smart watch can be reduced to reduce the power consumption.
[0016] In the technical solution, preferably, the region setting sub-unit is further configured
to set the region the center of which is a target point of the ring and the area of
which equals to the preset value to be the normal display region according to a received
rotation command.
[0017] In the technical solution, the determination angle of the G-sensor can be adjusted,
and accordingly the position of the normal display region on the smart watch can be
adjusted. For example, if the determination angle of the G-sensor is rotated 180°,
the determined normal display region is the bottom of the smart watch 100. Therefore,
the user can normally watch the content displayed on the smart watch 100 when the
user lays down. Certainly, the user can cause the normal display region to rotate
inside or outside any degrees to adjust the normal display region according to needs.
[0018] In the technical solution, preferably, the smart watch can further include an image
adjusting unit configured to determine an image region of the smart watch which is
displaying an image, overlap the center of the image region with the center of the
normal display region, and/or overlap the start margin of the image region with the
start margin of the normal display region, and/or overlap the end margin of the image
region with the end margin of the normal display region.
[0019] In the technical solution, the smart watch can automatically display the image in
the normal display region, to light the center of the image in normal brightness.
The smart watch can also overlap the start margin and/or the end margin of the image
with the start margin and/or the end margin of the normal display region, to light
the start portion or the end portion of the image in normal brightness, thereby facilitating
the user to browse the image from the start or end position, and also facilitating
the user to drag the image to view the other portion of the image.
[0020] In the technical solution, preferably, the brightness setting unit includes an area
determining sub-unit configured to determine whether or not the area of the image
region is greater than or equals to that of the normal display region, a brightness
assigning sub-unit configured to light the portion of the image region outside of
the normal display region in third preset brightness which is less than the first
preset brightness and light the region of the smart watch no image is displayed in
which in the second preset brightness when the area determining sub-unit determines
that the area of the image region is greater than or equals to that of the normal
display region. Wherein, the second preset brightness is less than the third preset
brightness.
[0021] In the technical solution, when the area of the image displayed on the smart watch
is greater than that of the normal display area, it indicates that a portion of the
displayed image is displayed outside of the normal display region. However, as the
center of the image still overlaps the center of the normal display region, a great
portion of the image can be displayed in normal brightness. The portion of the image
displayed outside of the normal display region can be displayed in the third preset
brightness, and the region of the smart watch no image is displayed in which is lighted
in the second preset brightness, thus power is saved, and also the display of the
smart watch has layering effect. The brightness gradually decreases from the image
displayed in the normal display region to the image displayed outside of the normal
display region and to the region no image is displayed in which, thus the user can
view the image more easily.
[0022] In the technical solution, preferably, the smart watch further includes an image
moving unit configured to move the image region according to a received image movement
command. The brightness assigning sub-unit is further configured to determine the
portion of the image region outside of the normal display region in real time, and
light the portion of the image region outside of the normal display region in the
third preset brightness.
[0023] In the technical solution, the user can move the image according to needs, to cause
the needed portion to be displayed in the normal display region (that is, to be displayed
in normal brightness). At the same time, during moving the image, the portion of the
image displayed outside of the normal display region is displayed in the third preset
brightness, while the brightness of the normal display region stays unchanged. Accordingly,
the portion which can be seen by the user can always stay in normal brightness, and
the portion which cannot be directly seen can always stay in lower brightness.
[0024] In the technical solution, preferably, the smart watch can further include a region
moving unit configured to move the normal display region according to a received region
movement command. The brightness assigning sub-unit is further configured to determine
the portion of the image region outside of the normal display region in real time,
and light the portion of the image region outside of the normal display region in
the third preset brightness.
[0025] In the technical solution, the user can move the normal display region according
to needs, to cause the normal display region to more meet user's watching habits.
For example, if the user does not vertically watch the content displayed on the smart
watch from up, and the user watches the content with the line of sight deviating from
the vertical direction 30°, the normal display region can be moved toward inside (that
is, user side) 30°. At the same time, during moving the region, the portion of the
image displayed outside of the normal display region is still displayed in the third
preset brightness, while the brightness of the normal display region stays unchanged.
Accordingly, the portion which can be seen by the user can always stay in normal brightness,
and the portion which cannot be directly seen can always stay in lower brightness.
[0026] In the technical solution, preferably, the smart watch further includes a brightness
adjusting unit configured to adjust the first preset brightness, the second preset
brightness, and/or the third preset brightness according to a received brightness
adjustment command.
[0027] In the technical solution, the user can adjust the brightness of each region of the
smart watch to satisfy actual needs.
[0028] In any of the above technical solutions, preferably, the smart watch can further
include a region adjusting unit configured to set the size and/or shape of the normal
display region according to a received region setting command.
[0029] In the technical solution, the user can adjust each parameter of the display region
according to needs, for example, prolong the display region or set the display region
to be circular, to cause the display region to have strong characteristic and operability.
[0030] In any of the technical solutions, preferably, the smart watch further includes a
face recognition unit configured to recognize face and/or eyes in real time when a
preset function is started, and determine the normal display region according to the
recognized face and/or eyes, to cause the normal display region to correspond to the
recognized face and/or eyes.
[0031] In the technical solution, after the face and/or eye recognition function is started,
a face recognition device and/or an eye recognition device of the smart watch can
be used to recognize the face and/or eyes, to accurately determine which region of
the smart watch is facing the user, thereby setting the region which is facing the
user to be the normal display region, and causing the normal display region to more
conform to user's vision.
[0032] In any of the technical solutions, preferably, the smart watch further includes a
temperature detecting unit configured to detect the temperature of the inside surface
of the smart watch, and reduce the brightness of the normal display region and/or
reduce the brightness of the other region when the temperature of the inside surface
is less than a preset temperature.
[0033] In the technical solution, whether or not the smart watch is worn by the user can
be determined by detecting the temperature of the inside surface of the smart watch.
If the temperature of the inside surface is less than a certain temperature, for example,
30 degrees, it indicates that at current time the smart watch is not worn by the user,
thus the brightness of all the regions can be reduced.
[0034] The present invention further provides a display method for a smart watch which includes:
step 202, monitoring a posture of the smart watch in real time and determining a normal
display region of the smart watch according to the posture, and step 204, displaying
the content to be displayed in the normal display region.
[0035] In the technical solution, one or more G-sensors can be employed to detect the posture
of the smart watch in space. For example, if lie flat, a ring of the smart watch is
parallel to the horizontal plane. When the ring of the smart watch is vertical to
the horizontal plane, it indicates that a user makes the smart watch up to watch the
time. When the user watches a ring arranged vertically, the user can only see a portion
of the ring which faces himself/herself. Thus when the smart watch is in this posture,
if the user watches the smart watch, the user can only see a portion of the smart
watch. Accordingly, the smart watch can determine which portion can be seen by the
user according to the current posture, for example, the top region, or the inner region
of the smart watch which is facing the user. This portion will be regarded as a normal
display region and will be lighted in first preset brightness (for example, normal
display brightness) to display an image, and the other region will be lighted in lower
brightness to display an image since the other region cannot be seen by the user.
[0036] In the technical solution, preferably, step 204 further includes setting the brightness
of the normal display region to be first preset brightness and setting the brightness
of the other region to be second preset brightness which is less than the first preset
brightness.
[0037] In the technical solution, when the user wants to view the image displayed in the
other region, the user can rotate his/her wrist to adjust the posture of the smart
watch, to make the smart watch to redefine the normal display region, thus the region
which can be seen by the user can be always lighted in normal brightness and the region
which cannot be seen by the user can be always lighted in lower brightness, thereby
reducing power consumption of the smart watch and prolonging the life of the battery
of the smart watch.
[0038] In the technical solution, preferably, step 202 includes: step 2022, computing the
included angle between the plane where the ring of the smart watch stays and the horizontal
plane and determining whether or not the included angle is within a preset angle range,
and step 2024, setting the region the center of which is a vertex of the ring within
the space and the area of which equals to a preset value to be the normal display
region when it is determined that the included angle is within the preset angle range.
[0039] In the technical solution, the posture of the smart watch can be determined by determining
the included angle between the ring of the smart watch and the horizontal plane. When
the included angle is within the preset angle range (e.g., 60° -90°), it indicates
that to a greater degree the smart watch is vertical to the horizontal plane, and
it can be determined that the user is watching the content displayed on the smart
watch, and the top portion of the smart watch will be set to be the normal display
region.
[0040] It should be noted that the way of determining the posture of the smart watch can
include but not limited to determination of the included angle.
[0041] In the technical solution, preferably, step 202 further includes step 2026, setting
the brightness of all the regions of the smart watch to be the second preset brightness
when it is determined that the included angle is less than a preset angle.
[0042] In the technical solution, when the included angle is less than the preset angle,
it indicates that to a greater degree the smart watch is parallel to the horizontal
plane, and it can be determined that at this point the user does not watch the content
displayed on the smart watch, thus the brightness of the whole display region of the
smart watch can be reduced to reduce the power consumption.
[0043] In the technical solution, preferably, the display method further includes setting
the region the center of which is a target point of the ring and the area of which
equals to a preset value to be the normal display region according to a received rotation
command.
[0044] In the technical solution, the determination angle of the G-sensor can be adjusted,
and accordingly the position of the normal display region on the smart watch is adjusted.
For example, if the determination angle of the G-sensor is rotated 180°, the determined
normal display region is the bottom of the smart watch. Therefore, the user can normally
watch the content displayed on the smart watch when the user lays down. Certainly,
the user can cause the normal display region to rotate inside or outside any degrees
to adjust the normal display region according to needs.
[0045] In the technical solution, preferably, step 204 further includes determining an image
region of the smart watch which is displaying an image, overlapping the center of
the image region with the center of the normal display region, and/or overlapping
the start margin of the image region with the start margin of the normal display region,
and/or overlapping the end margin of the image region with the end margin of the normal
display region.
[0046] In the technical solution, the smart watch can automatically display the image in
the normal display region, to light the center of the image in normal brightness.
The smart watch can also overlap the start margin and/or the end margin of the image
with the start margin and/or the end margin of the normal display region, to light
the start portion or the end portion of the image in normal brightness, thereby facilitating
the user to browse the image from the start or end position, and also facilitating
the user to drag the image to view the other portion of the image.
[0047] In the technical solution, preferably, step 204 further includes determining whether
or not the area of the image region is greater than or equals to that of the normal
display region, lighting the portion of the image region outside of the normal display
region in third preset brightness which is less than the first preset brightness and
lighting the region of the smart watch no image is displayed in which in the second
preset brightness when the area of the image region is greater than or equals to that
of the normal display region. Wherein, the second preset brightness is less than the
third preset brightness.
[0048] In the technical solution, when the area of the image displayed on the smart watch
is greater than that of the normal display region, it indicates that a portion of
the displayed image is displayed outside of the normal display region. However, as
the center of the image still overlaps the center of the normal display region, a
great portion of the image can be displayed in normal brightness. The portion of the
image outside of the normal display region can be displayed in the third preset brightness,
and the region of the smart watch no image is displayed in which is lighted in the
second preset brightness, thus power is saved, and also the display of the smart watch
has layering effect. The brightness gradually decreases from the image displayed in
the normal display region to the image displayed outside of the normal display region
and to the region no image is displayed in which, thus the user can view the image
more easily.
[0049] In the technical solution, preferably, the display method further includes moving
the image region according to a received image movement command, determining the portion
of the image region outside of the normal display region in real time, and lighting
the portion of the image region outside of the normal display region in the third
preset brightness.
[0050] In the technical solution, the user can move the image according to needs, to cause
the needed portion to be displayed in the normal display region (that is, to be displayed
in normal brightness). At the same time, during moving the image, the portion of the
image displayed outside of the normal display region is displayed in the third preset
brightness, while the brightness of the normal display region stays unchanged. Accordingly,
the portion which can be seen by the user can always stay in normal brightness, and
the portion which cannot be directly seen can always stay in lower brightness.
[0051] In the technical solution, preferably, the display method further includes moving
the normal display region according to a received region movement command, determining
the portion of the image region outside of the normal display region in real time,
and lighting the portion of the image region outside of the normal display region
in the third preset brightness.
[0052] In the technical solution, the user can move the normal display region according
to needs, to cause the normal display region to more meet user's watching habits.
For example, if the user does not vertically watch the content displayed on the smart
watch from up, and the user watches the content with the line of sight deviating from
the vertical direction 30°, the normal display region can be moved toward inside (that
is, user side) 30°. At the same time, during moving the region, the portion of the
image displayed outside of the normal display region is displayed in the third preset
brightness, while the brightness of the normal display region stays unchanged. Accordingly,
the portion which can be seen by the user can always stay in normal brightness, and
the portion which cannot be directly seen can always stay in lower brightness.
[0053] In the technical solution, preferably, the display method further includes adjusting
the first preset brightness, the second preset brightness, and/or the third preset
brightness according to a received brightness adjustment command.
[0054] In the technical solution, the user can adjust the brightness of each region of the
smart watch to satisfy actual needs.
[0055] In any of the above mentioned technical solutions, preferably, the display method
further includes setting the size and/or shape of the normal display region according
to a received region setting command.
[0056] In the technical solution, the user can adjust each parameter of the display region
according to needs, for example, prolong the display region or set the display region
to be circular, to cause the display region to have strong characteristic and operability.
[0057] In any of the above mentioned technical solutions, preferably, before step 202, the
display method further includes determining whether or not a preset function is started,
going to step 203 if started, and going to step 202 if not started. Step 203 includes
recognizing face and/or eyes in real time, and determining the normal display region
according to the recognized face and/or eyes, to cause the normal display region to
correspond to the recognized face and/or eyes.
[0058] In the technical solution, after the face and/or eye recognition function is started,
a face recognition device and/or an eye recognition device of the smart watch can
be used to recognize the face and/or eyes, to accurately determine which region of
the smart watch is facing the user, thereby setting the region which is facing the
user to be the normal display region, and causing the normal display region to more
conform to user's vision.
[0059] In any of the above mentioned technical solutions, preferably, the display method
further includes detecting the temperature of the inside surface of the smart watch,
and decreasing the brightness of the normal display region and/or decreasing the brightness
of the other region when the temperature of the inside surface is less than a preset
temperature.
[0060] In the technical solution, whether or not the smart watch 100 is worn by the user
can be determined by detecting the temperature of the inside surface of the smart
watch. If the temperature of the inside surface is less than a certain temperature,
for example, 30 degrees, it indicates that at current time the smart watch is not
worn by the user, thus the brightness of all the regions can be reduced.
[0061] By means of the technical solution, which region of a smart watch can be seen by
a user can be determined according to a posture of the smart watch, so that the brightness
of the region can be set to be normal brightness, and the other region which cannot
be seen by the user can be reduced, thereby prolonging the battery life of the smart
watch and improving user's experience.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS
[0063] To understand the above-mentioned purposes, features and advantages of the present
disclosure more clearly, the present disclosure will be further described in detail
below in combination with the accompanying drawings and the specific implementations.
It should be noted that, the embodiments of the present application and the features
in the embodiments may be combined with one another without conflicts.
[0064] Many specific details will be described below for sufficiently understanding the
present disclosure. However, the present disclosure may also be implemented by adopting
other manners different from those described herein. Accordingly, the protection scope
of the present invention is not limited by the specific embodiments disclosed below.
[0065] FIG. 2 is a block diagram of a smart watch in accordance with an exemplary embodiment
of the present invention.
[0066] As shown in FIG. 2, a smart watch 100 in accordance with an exemplary embodiment
of the present invention includes a posture monitoring unit 102 configured to monitor
a posture of the smart watch 100 in real time and determine a normal display region
of the smart watch 100 according to the posture, and a displaying unit 104 configured
to display content to be displayed in the normal display region. The posture monitoring
unit 102 can be one or more G-sensors and can detect the posture of the smart watch
100 in space. For example, if lie flat, a ring of the smart watch 100 is parallel
to the horizontal plane. When the ring of the smart watch 100 is vertical to the horizontal
plane, it indicates that a user makes the smart watch 100 up to watch the time. When
the user watches a ring arranged vertically, the user can only see a portion of the
ring which faces himself/herself. Thus when the smart watch 100 is in this posture,
if the user watches the smart watch, the user can only see a portion of the smart
watch 100. Accordingly, the smart watch 100 can determine which portion can be seen
by the user according to the current posture, for example, the top region, or the
inner region of the smart watch 100 which is facing the user. This portion will be
regarded as a normal display region and will be lighted in first preset brightness
(for example, normal display brightness) to display an image, and the other region
will be lighted in lower brightness to display an image since the other region cannot
be seen by the user.
[0067] Preferably, the displaying unit 104 includes a brightness setting unit 1042 configured
to set the brightness of the normal display region to be first preset brightness and
set the brightness of the other region to be second preset brightness which is less
than the first preset brightness.
[0068] When the user wants to view the image displayed in the other region, the user can
rotate his/her wrist to adjust the posture of the smart watch 100, to make the smart
watch 100 to redefine the normal display region, thus the region which can be seen
by the user can be always lighted in normal brightness and the region which cannot
be seen by the user can be always lighted in lower brightness, thereby reducing power
consumption of the smart watch 100 and prolonging the life of the battery of the smart
watch 100.
[0069] Preferably, the posture monitoring unit 102 includes an included angle determining
sub-unit 1022 configured to compute the included angle between the plane where the
ring of the smart watch 100 stays and the horizontal plane and determine whether or
not the included angle is within a preset angle range, and a region setting sub-unit
1024 configured to set the region the center of which is a vertex of the ring within
the space and the area of which equals to a preset value to be the normal display
region when the included angle determining sub-unit 1022 determines that the included
angle is within the preset angle range.
[0070] Specifically, the posture of the smart watch 100 can be determined by determining
the included angle between the ring of the smart watch 100 and the horizontal plane.
When the included angle is within the preset angle range (e.g., 60° - 90°), it indicates
that to a greater degree the smart watch 100 is vertical to the horizontal plane,
and it can be determined that the user is watching the content displayed on the smart
watch 100, and the top portion of the smart watch 100 is set to be the normal display
region.
[0071] It should be noted that the way of determining the posture of the smart watch 100
can include but not limited to determination of the included angle.
[0072] Preferably, the brightness setting unit 1042 is further configured to set the brightness
of all the regions of the smart watch 100 to be the second preset brightness when
the included angle determining sub-unit 1022 determines that the included angle is
not within the preset angle range.
[0073] When the included angle is less than the preset angle, it indicates that to a greater
degree the smart watch 100 is parallel to the horizontal plane, and it can be determined
that at this point the user does not watch the content displayed on the smart watch
100, thus the brightness of the whole display region of the smart watch 100 can be
reduced to reduce the power consumption.
[0074] Preferably, the region setting sub-unit 1024 is further configured to set the region
the center of which is a target point of the ring and the area of which equals to
a preset value to be the normal display region according to a received rotation command.
[0075] The determination angle of the G-sensor can be adjusted, and accordingly the position
of the normal display region on the smart watch 100 can be adjusted. For example,
if the determination angle of the G-sensor is rotated 180°, the determined normal
display region is the bottom of the smart watch 100. Therefore, the user can normally
watch the content displayed on the smart watch 100 when the user lays down. Certainly,
the user can cause the normal display region to rotate inside or outside any degrees
to adjust the normal display region according to needs.
[0076] Preferably, the smart watch 100 can further include an image adjusting unit 106 configured
to determine an image region of the smart watch 100 which is displaying an image,
overlap the center of the image region with the center of the normal display region,
and/or overlap the start margin of the image region with the start margin of the normal
display region, and/or overlap the end margin of the image region with the end margin
of the normal display region.
[0077] The smart watch 100 can automatically display the image in the normal display region,
to light the center of the image in normal brightness. The smart watch 100 can also
overlap the start margin and/or the end margin of the image with the start margin
and/or the end margin of the normal display region, to light the start portion or
the end portion of the image in normal brightness, thereby facilitating the user to
browse the image from the start or end position, and also facilitating the user to
drag the image to view the other portion of the image.
[0078] Preferably, the brightness setting unit 1042 includes an area determining sub-unit
10422 configured to determine whether or not the area of the image region is greater
than or equals to that of the normal display region, a brightness assigning sub-unit
10424 configured to light the portion of the image region outside of the normal display
region in third preset brightness which is less than the first preset brightness and
light the region of the smart watch no image is displayed in which in the second preset
brightness when the area determining sub-unit 10422 determines that the area of the
image region is greater than or equals to that of the normal display region. Wherein,
the second preset brightness is less than the third preset brightness.
[0079] If the area of the image displayed on the smart watch 100 is greater than that of
the normal display area, it indicates that a portion of the displayed image is displayed
outside of the normal display region. However, as the center of the image still overlaps
the center of the normal display region, a great portion of the image can be displayed
in normal brightness. The portion of the image displayed outside of the normal display
region can be displayed in the third preset brightness, and the region of the smart
watch 100 no image is displayed in which is lighted in the second preset brightness,
thus power is saved, and also the display of the smart watch 100 has layering effect.
The brightness gradually decreases from the image displayed in the normal display
region to the image displayed outside of the normal display region and to the region
no image is displayed in which, thus the user can view the image more easily.
[0080] Preferably, the smart watch 100 further includes an image moving unit 108 configured
to move the image region according to a received image movement command. The brightness
assigning sub-unit 10424 is further configured to determine the portion of the image
region outside of the normal display region in real time, and light the portion of
the image region outside of the normal display region in the third preset brightness.
[0081] The user can move the image according to needs, to cause the needed portion to be
displayed in the normal display region (that is, to be displayed in normal brightness).
At the same time, during moving the image, the portion of the image displayed outside
of the normal display region is displayed in the third preset brightness, while the
brightness of the normal display region stays unchanged. Accordingly, the portion
which can be seen by the user can always stay in normal brightness, and the portion
which cannot be directly seen can always stay in lower brightness.
[0082] Preferably, the smart watch 100 can further include a region moving unit 110 configured
to move the normal display region according to a received region movement command.
The brightness assigning sub-unit 10424 is further configured to determine the portion
of the image region outside of the normal display region in real time, and light the
portion of the image region outside of the normal display region in the third preset
brightness.
[0083] The user can move the normal display region according to needs, to cause the normal
display region to more meet user's watching habits. For example, if the user does
not vertically watch the content displayed on the smart watch 100 from up, and the
user watches the content with the line of sight deviating from the vertical direction
30°, the normal display region can be moved toward inside (that is, user side) 30°.
At the same time, during moving the region, the portion of the image displayed outside
of the normal display region is still displayed in the third preset brightness, while
the brightness of the normal display region stays unchanged. Accordingly, the portion
which can be seen by the user can always stay in normal brightness, and the portion
which cannot be directly seen can always stay in lower brightness.
[0084] Preferably, the smart watch 100 further includes a brightness adjusting unit 112
configured to adjust the first preset brightness, the second preset brightness, and/or
the third preset brightness according to a received brightness adjustment command.
[0085] The user can adjust the brightness of each region of the smart watch 100 to satisfy
actual needs.
[0086] Preferably, the smart watch 100 can further include a region adjusting unit 114 configured
to set the size and/or shape of the normal display region according to a received
region setting command.
[0087] The user can adjust each parameter of the display region according to needs, for
example, prolong the display region or set the display region to be circular, to cause
the display region to have strong characteristic and operability.
[0088] Preferably, the smart watch 100 further includes a face recognition unit 116 configured
to recognize face and/or eyes in real time when a preset function is started, and
determine the normal display region according to the recognized face and/or eyes,
to cause the normal display region to correspond to the recognized face and/or eyes.
[0089] After the face and/or eye recognition function is started, a face recognition device
and/or an eye recognition device of the smart watch 100 can be used to recognize the
face and/or eyes, to accurately determine which region of the smart watch 100 is facing
the user, thereby setting the region which is facing the user to be the normal display
region, and causing the normal display region to more conform to user's vision.
[0090] Preferably, the smart watch 100 further includes a temperature detecting unit 118
configured to detect the temperature of the inside surface of the smart watch 100,
and decrease the brightness of the normal display region and/or decrease the brightness
of the other region when the temperature of the inside surface is less than a preset
temperature.
[0091] Whether or not the smart watch 100 is worn by the user can be determined by detecting
the temperature of the inside surface of the smart watch 100. If the temperature of
the inside surface is less than a certain temperature, for example, 30 degrees, it
indicates that at current time the smart watch 100 is not worn by the user, thus the
brightness of all the regions can be reduced.
[0092] FIG. 3 is a flow chart of a display method for a smart watch in accordance with an
exemplary embodiment of the present invention.
[0093] As shown in FIG. 3, a display method for a smart watch in accordance with an exemplary
embodiment of the present invention includes: step 202, monitoring a posture of the
smart watch in real time and determining a normal display region of the smart watch
according to the posture, and step 204, displaying content to be displayed in the
normal display region.
[0094] One or more G-sensors can be employed to detect the posture of the smart watch in
a space. For example, if lie flat, a ring of the smart watch is parallel to the horizontal
plane. When the ring of the smart watch is vertical to the horizontal plane, it indicates
that a user makes the smart watch up to watch the time. When the user watches a ring
arranged vertically, the user can only see a portion of the ring which faces himself/herself.
Thus when the smart watch is in this posture, if the user watches the smart watch,
the user can only see a portion of the smart watch. Accordingly, the smart watch can
determine which portion can be seen by the user according to the current posture,
for example, the top region, or the inner region of the smart watch which is facing
the user. This portion will be regarded as a normal display region and will be lighted
in first preset brightness (for example, normal display brightness) to display an
image, and the other region will be lighted in lower brightness to display an image
since the other region cannot be seen by the user.
[0095] When the user wants to view the image displayed in the other region, the user can
rotate his/her wrist to adjust the posture of the smart watch, to make the smart watch
to redefine the normal display region, thus the region which can be seen by the user
can be always lighted in normal brightness and the region which cannot be seen by
the user can be always lighted in lower brightness, thereby decreasing power consumption
of the smart watch and prolonging the life of the battery of the smart watch.
[0096] Preferably, step 202 includes: step 2022, computing the included angle between the
plane where the ring of the smart watch stays and the horizontal plane and determining
whether or not the included angle is within a preset angle range, and step 2024, setting
the region the center of which is a vertex of the ring within the space and the area
of which equals to a preset value to be the normal display region when it is determined
that the included angle is within the preset angle range.
[0097] Preferably, step 204 further includes setting the brightness of the normal display
region to be the first preset brightness and setting the brightness of the other region
to be second preset brightness which is less than the first preset brightness.
[0098] Specifically, the posture of the smart watch can be determined by determining the
included angle between the ring of the smart watch and the horizontal plane. When
the included angle is within the preset angle range (e.g., 60° -90°), it indicates
that to a greater degree the smart watch is vertical to the horizontal plane, and
it can be determined that the user is watching the content displayed on the smart
watch, and the top portion of the smart watch will be set to be the normal display
region.
[0099] It should be noted that the way of determining the posture of the smart watch can
include but not limited to determination of the included angle.
[0100] Preferably, step 202 further includes step 2026, setting the brightness of all the
regions of the smart watch to be the second preset brightness when it is determined
that the included angle is less than a preset angle.
[0101] When the included angle is less than the preset angle, it indicates that to a greater
degree the smart watch is parallel to the horizontal plane, and it can be determined
that at this point the user does not watch the content displayed on the smart watch
100, thus the brightness of the whole display region of the smart watch 100 can be
decreased to decrease the power consumption.
[0102] Preferably, the display method further includes setting the region the center of
which is a target point of the ring and the area of which equals to a preset value
to be the normal display region according to a received rotation command.
[0103] The determination angle of the G-sensor can be adjusted, and accordingly the position
of the normal display region on the smart watch is adjusted. For example, if the determination
angle of the G-sensor is rotated 180°, the determined normal display region is the
bottom of the smart watch. Therefore, the user can normally watch the content displayed
on the smart watch when the user lays down. Certainly, the user can cause the normal
display region to rotate inside or outside any degrees to adjust the normal display
region according to needs.
[0104] Preferably, step 204 further includes determining an image region of the smart watch
which is displaying an image, overlapping the center of the image region with the
center of the normal display region, and/or overlapping the start margin of the image
region with the start margin of the normal display region, and/or overlapping the
end margin of the image region with the end margin of the normal display region.
[0105] The smart watch can automatically display the image in the normal display region,
to light the center of the image in normal brightness. The smart watch can also overlap
the start margin and/or the end margin of the image with the start margin and/or the
end margin of the normal display region, to light the start portion or the end portion
of the image in normal brightness, thereby facilitating the user to browse the image
from the start or end position, and also facilitating the user to drag the image to
view the other portion of the image.
[0106] Preferably, step 204 further includes determining whether or not the area of the
image region is greater than or equals to that of the normal display region, lighting
the portion of the image region outside of the normal display region in third preset
brightness which is less than the first preset brightness and lighting the region
of the smart watch no image is displayed in which in the second preset brightness
when the area of the image region is greater than or equals to that of the normal
display region. Wherein, the second preset brightness is less than the third preset
brightness.
[0107] When the area of the image displayed on the smart watch is greater than that of the
normal display region, it indicates that a portion of the displayed image is displayed
outside of the normal display region. However, as the center of the image still overlaps
the center of the normal display region, a great portion of the image can be displayed
in normal brightness. The portion of the image outside of the normal display region
can be displayed in the third preset brightness, and the region of the smart watch
no image is displayed in which is lighted in the second preset brightness, thus power
is saved, and also the display of the smart watch has layering effect. The brightness
gradually decreases from the image displayed in the normal display region to the image
displayed outside of the normal display region and to the region no image is displayed
in which, thus the user can view the image more easily.
[0108] Preferably, the display method further includes moving the image region according
to a received image movement command, determining the portion of the image region
outside of the normal display region in real time, and lighting the portion of the
image region outside of the normal display region in the third preset brightness.
[0109] The user can move the image according to needs, to cause the needed portion to be
displayed in the normal display region (that is, to be displayed in normal brightness).
At the same time, during moving the image, the portion of the image displayed outside
of the normal display region is displayed in the third preset brightness, while the
brightness of the normal display region stays unchanged. Accordingly, the portion
which can be seen by the user can always stay in normal brightness, and the portion
which cannot be directly seen can always stay in lower brightness.
[0110] Preferably, the display method further includes moving the normal display region
according to a received region movement command, determining the portion of the image
region outside of the normal display region in real time, and lighting the portion
of the image region outside of the normal display region in the third preset brightness.
[0111] The user can move the normal display region according to needs, to cause the normal
display region to more meet user's watching habits. For example, if the user does
not vertically watch the content displayed on the smart watch from up, and the user
watches the content with the line of sight deviating from the vertical direction 30°,
the normal display region can be moved toward inside (that is, user side) 30°. At
the same time, during moving the region, the portion of the image displayed outside
of the normal display region is displayed in the third preset brightness, while the
brightness of the normal display region stays unchanged. Accordingly, the portion
which can be seen by the user can always stay in normal brightness, and the portion
which cannot be directly seen can always stay in lower brightness.
[0112] Preferably, the display method further includes adjusting the first preset brightness,
the second preset brightness, and/or the third preset brightness according to a received
brightness adjustment command.
[0113] The user can adjust the brightness of each region of the smart watch to satisfy actual
needs.
[0114] In any of the above technical solutions, preferably, the display method further includes
setting the size and/or shape of the normal display region according to a received
region setting command.
[0115] The user can adjust each parameter of the display region according to needs, for
example, prolong the display region or set the display region to be circular, to cause
the display region to have strong characteristic and operability.
[0116] Preferably, before step 202, the display method further includes determining whether
or not a preset function is started, going to step 203 if started, and going to step
202 if not started. Step 203 includes recognizing face and/or eyes in real time, and
determining the normal display region according to the recognized face and/or eyes,
to cause the normal display region to correspond to the recognized face and/or eyes.
[0117] After the face and/or eye recognition function is started, a face recognition device
and/or an eye recognition device of the smart watch can be used to recognize the face
and/or eyes, to accurately determine which region of the smart watch is facing the
user, thereby setting the region which is facing the user to be the normal display
region, and causing the normal display region to more conform to user's vision.
[0118] Preferably, the display method further includes detecting the temperature of the
inside surface of the smart watch, and decreasing the brightness of the normal display
region and/or decreasing the brightness of the other region when the temperature of
the inside surface is less than a preset temperature.
[0119] Whether or not the smart watch is worn by the user can be determined by detecting
the temperature of the inside surface of the smart watch. If the temperature of the
inside surface is less than a certain temperature, for example, 30 degrees, it indicates
that at current time the smart watch is not worn by the user, thus the brightness
of all the regions can be decreased.
[0120] FIG. 4 is a detailed flow chart of a display method for a smart watch in accordance
with an exemplary embodiment of the present invention.
[0121] As shown in FIG. 4, a display method for a smart watch in accordance with an exemplary
embodiment of the present invention specifically includes the following steps.
[0122] In step 302, determining a posture of the smart watch, determining the area of the
top region of the smart watch if the smart watch is in a used posture, and determining
the top region to be a normal display region (viewable region).
[0123] In step 304, determining the area of the region needed by the content displayed by
the smart watch.
[0124] In step 306, overlapping the displayed content with the normal display region.
[0125] In step 308, determining whether or not the area of the displayed content is greater
than that of the normal display region.
[0126] In step 310, lighting the displayed content in normal brightness if the area of the
displayed content is less than that of the normal display region.
[0127] In step 312, reducing the brightness of the region no content is displayed in which
or executing a smart wake operation on the region no content is displayed in which.
[0128] In step 314, lighting the content displayed in the normal display region normally
and reducing the brightness of the content displayed outside of the normal display
region if the area of the displayed content is greater than that of the normal display
region, and returning to step 312.
[0129] FIG. 5 is a schematic view showing that a user is watching a smart watch in accordance
with an exemplary embodiment of the present invention.
[0130] As shown in FIG. 5, when the user (can be understood to be an eye 402 herein) watches
the smart watch 100, as the smart watch is circular, the whole outside of the smart
watch 100 can be used as the display region, but the region which can be directly
seen by the eye 402 is just one range which is not greater than 180° in theory, that
is the effective range of sight. When the whole region of the smart watch is used
to display content, the eye 402 can only see a portion of content within the effect
range of sight, and the content displayed in the other region cannot be directly seen.
Thus, the brightness of the region which cannot be directly seen can be reduced, and
only the brightness of the region within the effect range of sight can be kept in
normal brightness, thereby to a greatest degree the power consumption of the smart
watch 100 is reduced, user's use is not affected, and the battery life is prolonged.
[0131] FIGs. 6A -6J are schematic views showing determination of a normal display region
in accordance with an exemplary embodiment of the present invention.
[0132] As shown in FIG. 6A, when the user watches the smart watch 100, normally, the smart
watch 100 is vertical to a horizontal plane 410. At this point, an included angle
408 between a ring 414 of the smart watch 100 and the horizontal plane 410 can be
detected. If the included angle 408 is greater than a preset angle, it indicates that
to a greater degree the smart watch 100 is vertical to the horizontal plane 410. For
example, in FIG. 6A, the included angle 408 is 90°, at this point it can be determined
that the user is watching the smart watch 100, thus the top region of the smart watch
100 will be set to be the normal display region.
[0133] As shown in FIG. 6B, normally, when the user does not watch the smart watch 100,
the smart watch 100 is worn on the wrist of the user and the arm of the user is vertical
to the ground, or the smart watch 100 is laid flat. Under above conditions, the included
angle 408 between the ring 414 of the smart watch 100 and the horizontal plane 410
is smaller. Thus, when the included angle 408 is smaller, it can be determined that
the smart watch 100 is not used. For example, in FIG. 6B, the included angle 408 is
0°, the ring 414 of the smart watch 100 is parallel to the horizontal plane 410, at
this point the brightness of all the regions of the smart watch 100 can be reduced.
[0134] After illustrating the change of the normal display region 404 when the smart watch
100 is rotated in space, the following will mainly illustrate the intelligent determination
of the normal display region 404 (the following will give an illustration according
to a vertex 420 corresponding to the center of the normal display region) when the
smart watch 100 is rotated in a vertical plane (that is, the user rotates his/her
wrist to watch the smart watch).
[0135] As shown in FIG. 6C, a G-sensor 416 can be used to determine a fixed point of the
smart watch 100.
[0136] The G-sensor 416 can be arranged at any position of the ring 414. A computing equation
L=R ×sinα can be set, wherein R is the radius of the ring 414, α is the included angle
between a connection line formed by the center of the ring 414 and the center of the
G-sensor 416 and a vertical line 422 (automatically determined as an acute angle),
L is a movement distance of the vertical line 422 across the center of the G-sensor
416 in a preset direction 424. After moving the vertical line 422 the distance L toward
the center of the ring 414, two intersection points are formed between the vertical
line 422 and the ring 414. Wherein, the intersection point arranged above the horizontal
plane where the G-sensor 416 stays, that is the vertex 420, can be taken as the center
of the normal display region 404.
[0137] For example, the G-sensor 416 is arranged at a point of tangency formed by the vertical
line 422 and the ring 414. A connection line formed by the center of the ring 414
and the G-sensor 416 is vertical to the vertical line 422. According to the equation
it can be determined that L=Rsin90°=R. That is, after moving the vertical line 422
R in the preset direction 424, the intersection point formed by the vertical line
422 and the ring 414 and arranged above the horizontal plane is the vertex 420.
[0138] As shown in FIG. 6D, when the ring 414 is rotated in the vertical plane (normally,
the user rotates his/her wrist), for example, rotated toward one side 45°, the position
of the G-sensor 416 in the space changes accordingly. It can be determined that the
included angle between the connection line formed by the center of the ring 414 and
the G-sensor 416 and the vertical line 422 is 45° determined by 90° minus 45°. Furthermore,
according to the equation L=Rsin45°, it can be determined that L is
that is, after moving the vertical line 422 across the G-sensor 416
toward the center of the ring 414, the intersection point formed by the vertical
line 422 and the ring 414 and arranged above the horizontal plane is the vertex 420.
Certainly, a number of G-sensors may be employed to determine the vertex 420. For
example, as shown in FIG. 6E, two G-sensors, the first G-sensor 417 and the second
G-sensor 418 are employed. The two G-sensors are respectively arranged at two ends
of a central line across the the center of the ring 414. As the position information
of the two G-sensors are known, the connection line formed by the two G-sensors can
be obtained, then the center of the connection line can be obtained. There are two
intersection points between the vertical line 422 across the center and the ring 414,
wherein the intersection point arranged above the horizontal plane where any of the
G-sensors stays is the vertex 420. As shown in FIG. 6F, when the ring 414 is rotated
in the vertical plane (normally, the user rotates his/her wrist), the center of the
connection line formed by the two G-sensors still overlaps the center of the ring
414, and there are two intersection points between the vertical line 422 across the
center of the connection line formed by the two G-sensors and the ring 414, wherein
the intersection point arranged above the horizontal plane where any of the G-sensors
stays is the vertex 420.
[0139] The user can adjust the determination angle of the G-sensor according to needs. For
example, when one G-sensor is employed, if the determination angle of the G-sensor
is rotated 180°, the determination way is similar to FIG. 6C and FIG. 6D, and the
difference is that the intersection point formed by the vertical line 422 and the
ring 414 and arranged below the horizontal plane where the G-sensor 416 stays is set
to be the center of the normal display region 404.
[0140] Similarly, the user can rotate the determination angle of he G-sensor any degrees
to cause the normal display region 404 to be proper for watching. After the user adjusts
the determination angle θ of the G-sensor (among 0° -360°), the equation used for
determining the vertex 420 changes accordingly. At this point L=Rsin(90°+β) -Rsinθ,
wherein R is the radius of the ring 414, β is the rotation angle of the ring 414 within
the vertical plane (among 0° -180°), L is the movement distance of the vertical line
422 across the center of the G-sensor in the preset direction 424 (L can be a negative
value, and when the vertical line 422 is moved toward a direction opposite to the
preset direction 424, L is a negative value), and θ is the adjusted determination
angle of the G-sensor. When θ is within 0° -90 or within 270° -360°, the intersection
point between the vertical line 422 and the ring 414 and arranged above the horizontal
plane where the G-sensor 414 stays is set to be the vertex 420. When θ is within 90°
-270°, the intersection point formed by the vertical line 422 and the ring 414 and
arranged below the horizontal plane where the G-sensor 414 stays is set to be the
vertex 420.
[0141] As shown in FIG. 6H, the determination angle of the G-sensor can be rotated toward
one side 30°, that is θ=30°, then at this point L=Rsin(90° +0) -Rsin30°=0.5R. That
is, after moving the vertical line 422 across the center of the G-sensor 0.5R in the
preset direction 424, the intersection point formed by the vertical line 422 and the
ring 414 and arranged above the horizontal plane where the G-sensor 414 stays is the
vertex 420.
[0142] As shown in FIG. 6I, the ring 414 is rotated 60° within the vertical plane, that
is β=60°, at this point L=Rsin(90° +60°) -Rsin30°=0. That is, at this point the intersection
point formed by the vertical line 422 and the ring 414 and arranged above the horizontal
plane where the G-sensor 414 stays is the vertex 420, and the movement distance of
the vertical line 422 is zero.
[0143] As shown in FIG. 6J, if the determination angle of the G-sensor is rotated toward
one side 330°, that is θ=330°, then the ring 414 is rotated 180° within the vertical
plane, that is β=180°, at this point L=Rsin(90° +180°) -Rsin330°=-0.5R. That is, after
moving the vertical line 422 across the center of the G-sensor 416 0.5R in a direction
opposite to the preset direction 424, the intersection point formed by the vertical
line 422 and the ring 414 and arranged above the horizontal plane where the G-sensor
414 stays is the vertex 420.
[0144] For FIG. 6G, the determination angle of the G-sensor is rotated 180°, that is θ=180°,
and L=Rsin(90° +0) -Rsin180°=R. That is, after moving the vertical line 422 R in the
preset direction 424, the intersection points between the vertical line 422 and the
ring 414 are respectively arranged at the top and bottom of the ring 414 in the space.
As 180° falls within 90° -270°, the bottom of the ring 414 in the space is set to
be the vertex 420 and the normal display region 404 is set according to the vertex
420.
[0145] It should be noted that the method of determining the vertex 420 can include but
not limited to the above methods.
[0146] FIGs. 7A -7D are schematic views showing display of a smart watch in accordance with
an exemplary embodiment of the present invention.
[0147] As shown in FIG. 7A, if the eye 402 watches the smart watch 402 from up, then the
region of the smart watch 100 which can be directly seen by the eye 402 is the normal
display region. The region is lighted in first preset brightness (normal brightness),
and the other region 406 (which cannot be directly seen by the eye 402) is lighted
in second preset brightness. Therefore, it can ensure that the brightness of the region
of the smart watch which can be directly seen by the user is normal, and the brightness
of the region which cannot be directly seen by the user is lower or the region which
cannot be directly seen by the user is not lighted.
[0148] When the area of the image displayed on the smart watch 100 is less than that of
the normal display region 404, the smart watch 100 automatically overlaps the center
of the image with the center of the normal display region 404, to cause the whole
image to be lighted in normal brightness.
[0149] As shown in FIG. 7B, if the area of the image displayed on the smart watch is greater
than that of the normal display region 404, the portion of the image displayed outside
of the normal display region 404 is an intersection region 412. Then the brightness
of the normal display region 404 can stay unchanged, and the brightness of the intersection
region 412 can be set to be third preset brightness which falls in between the first
preset brightness and the second preset brightness, therefore on the whole the brightness
of the smart watch 100 gradually decreases from the normal display region 304 to the
intersection region 412 and to the other region 406.
[0150] The center of the image displayed in the normal display region 404 can overlap the
center of the normal display region 404. When the area of the image is less than that
of the normal display region 404, to facilitate the user to view the image, the image
can be displayed in the center of the normal display region 404. The start or end
margin of the image can also be set to overlap the start or end margin of the normal
display region 404. Thus, when the area of the image is greater than that of the normal
display region, the user can view the image from the start or end portion of the image,
thereby facilitating the user to drag the image from one end to browse the whole image.
[0151] As shown in FIG. 7C, if the user wants to view the intersection region 412, the user
can move the image to cause the intersection region 412 to be moved into the normal
display region 404. For example, when moving the image in clockwise, then the intersection
region 412 in clockwise of the normal display region 404 will increase, and the intersection
region 412 in anticlockwise of the normal display region 404 will decrease, thereby
ensuring that the brightness of the content currently viewed by the user is always
normal, and there is no need to increase the brightness of the other region which
cannot be directly seen by the user.
[0152] As shown in FIG. 7D, the user can adjust the position of the normal display region
404 on the smart watch 100 according to watching habits. This can be realized by directly
adjusting the position of the normal display region 404, and can also be realized
by adjusting the determination method for the G-sensor. Therefore, the intelligent
display region can be set to be outside of the top of the smart watch 100, for example,
rotated a certain degrees in user's direction (rotated toward inner side), thus the
eye 402 can see the normal display region 404 by tilting a smaller angle.
[0153] The above illustrates the technical solution of the present invention in conjunction
with the accompanying drawings. In related art, the display screen takes up the whole
outside of the smart watch to display content. However, the user can only see a part
of the content, and lighting the region which cannot be directly seen will bring a
waste of power. By means of the technical solution of the present invention, according
to the posture of the smart watch, which region can be seen by the user can be determined,
so that the brightness of the region can be set to be normal brightness, and the brightness
of the other region which cannot be directly seen can be reduced, thereby prolonging
the battery life of the smart watch and improving user's experience.

only used to describe purposes, and should not be understood to indicate or imply
importance. The term "a number of" indicates two or more than two except additional
specific definition.
